Bouldering-only gyms have a lot going for them. They’re often small and simple: fill out a waiver, and off you go — no auto-belay lectures or anxiety-inducing belay tests. The terrain is usually dense with problems, and there might be a light-up training board or even Treadwall. You can train for whatever your goals are, be they bouldering your hardest, indoors or out, or sport-climb redpoints.
And indoor bouldering is just plain fun, from seeking out the smallest holds you can pull on to hucking the biggest dynos you can stick to getting weird and wild with comp-style upside-down or parkour problems. There’s no feeling better than finally cracking the beta with friends — both old and new ones you just made as you all work the moves together.
Oddly enough, bouldering gyms weren’t always a thing. Only in the past 2 decades have they begun to pop up around the United States, though they’re now nearly ubiquitous. I can count at least 10 within a 1.5-hour drive in my home on the Front Range, Colorado!
With an eye toward the very best, most unique bouldering gyms across the country, we picked seven favorites, some of them OG venues like The Spot Boulder in Colorado and some new school like The Boulder Field in Sacramento.
In addition to focusing on bouldering only, criteria included varied terrain, history, openness and accessibility, community and inclusivity, geographic location, and perhaps most important of all, the quality and reputation of the setting. You can have the best bouldering walls on Earth, but if the setting is bad, it just won’t matter.
